Rules for constructing a graph

• Graph paper should always be used
• Each box should represent the same increment or
  value
• The scales on each axis should be spaced apart as
  far as possible
• While still providing space for all data points
  to be graphed
• A line of best fit should be used to summarize
  data
• If more than one set of data is shown, then a
  legend should be provided

Analyzing data

• Graphs are constructed to illustrate the
  relationships between variables.
• From a graph you should be able to state a
  general trend between variables.
• You should be able to interpolate other data
  points using the line of best fit.
• You should also be able to extrapolate data that
  is not shown by extending the line of best fit.
